After filing my return for 2021, I realized there was an error in my 2020 return -- basically, I had forgotten to deduct capital losses carried forward from 2019. I filed an amendment for the 2020 return back in May 2022, but I haven't heard anything from the IRS yet (it doesn't show up on the amended tax return status website either). The error also affects my 2021 return, but I was advised to wait till the 2020 amendment was processed. But, given how long it is taking, I am wondering if I should file the 2021 amendment as well?
